That is, the video signal switching unit 400 can establish transmission paths of the two video sources for the analog broadcast signal and the digital broadcast signal in different directions.
- a user selectively watches an analog broadcast signal or a digital broadcast signal he or she wants, while another video signal can be recorded on a storage medium such as the video tape 131. Furthermore, there is an advantage to recording the analog and digital broadcast signals on a low-priced storage medium such as the video tape 131 since the manufacturing cost of the combination system can be reduced.
- an exemplary embodiment of the present invention records one of the broadcast signals output from the respective tuners capable of receiving analog and digital broadcast signals while reproducing the other video signal through a display device, so a user can record a broadcast program corresponding to the digital broadcast signal while watching a broadcast program corresponding to the analog broadcast signal or record the broadcast program corresponding to the analog broadcast signal while watching the broadcast program corresponding to the digital broadcast signal.
- the present invention eliminates the conventional storage media respectively corresponding to the analog and digital broadcast signals, as well as not requires a high-priced storage medium such as hard disc drive in order to integrate the storage media.
